Portable pH/ORP/Temp Meter PH300

Short Description:

Portable pH/ORP/Temp Meter is a handheld, multi‑parameter instrument for on‑site measurement of acidity (pH), oxidation‑reduction potential (ORP), and temperature in water and other aqueous solutions. It features a single, interchangeable probe that houses high‑impedance glass pH sensing elements, a platinum ORP band, and a built‑in temperature sensor (ATC) for automatic compensation, ensuring accurate readings across the full 0–14 pH range and ±2000 mV ORP. The rugged, waterproof (IP67) housing withstands harsh field conditions, and the backlit LCD displays all three parameters simultaneously. The meter stores up to 500 data points with time/date stamps and offers USB or Bluetooth connectivity for data transfer and analysis. Powered by rechargeable batteries or standard AA cells, it supports long‑duration field campaigns. Common applications include environmental monitoring (rivers, lakes, groundwater), wastewater treatment, aquaculture, swimming pools, hydroponics, and industrial process control. Key benefits include fast response, one‑touch calibration, and low maintenance. The portable pH/ORP/temp meter is an essential tool for field professionals who need reliable, real‑time water quality data without the need for benchtop laboratory instruments. It helps optimize chemical dosing (acid/alkali, chlorine/ozone), ensure regulatory compliance, and monitor aquatic health efficiently.
